As you can see on my previous screenshot, I changed NS records a couple of days ago but cf.sjr.dev said that there are no IP addresses for ayurvedanow.fit.
If you don’t want to use Cloudflare you need to change your nameservers at your registrar. Most hosting companies have a way to use a 3rd party DNS (like Cloudflare) and simply point individual records for host names to the specific sites.
It’s not working because your domain registration at GoDaddy says to use Cloudflare’s name servers for ayurvedanow.fit. You can not use the Cloudflare name servers to override what the domain registration said to use for ayurvedanow.fit.
As cscharff said, you need DNS records here if you want your site to work. You have two choices:
Copy all the DNS records at your host (Ionos?) and put them in your Cloudflare account.
Go to GoDaddy and set your name servers to the ui-dns ones.
